These Poly Resin pen blanks are offered in a range of unique patterns not available in other materials. This pattern is called Tiger Lily, an alternating arrangement of orange, white and black running lengthwise through the blank. The blanks are cast using a special technique that creates encapsulated ''capillaries'' running through the interior. The result is a blank with a uniform striped appearance all the way around the perimeter, regardless of the final diameter. Polyester resin turns well with sharp tools and takes a fantastic polish. The blank arrives pre-rounded for fast turning on the lathe.
